Altering database table

[udi h bauman]

Hi,   I'm using the Hypersonic database that arrived with Orion.   I've added a field to an entity bean (in the ejb-jar.xml) yet it seem like Orion didn't update the database structure.   How can I alter the table structure? I there a way to re-create it?   I understand the Hypersonic database is deceased or something, but is there a live console somewhere?     Thanks, udi
